Cataract

Brief summary

This will be a single center, non comparison clinical trial. Fifty study patients will have the Symfony IOL implanted in their dominant eye and a +3,25D Tecnis Multifocal in their non-dominant eye. The investigators will be evaluated vision at distance, intermediate and near as well as assessing patient satisfaction and spectacle independence.

Detailed description

Each study patient will undergo the same routine cataract extraction procedure in each eye. In their dominant eye a Tecnis Symfony IOL will be implanted and in the non dominant eye, a Tecnis +3.25D Multifocal implanted. The surgeries will be within 2 days of each other. Every patient will receive same postoperative instructions and medications. The aim is to investigate the potential benefits of implanting two different IOL's to give the patient a wider range of near vision with decreased risk of haloing and glare to enable them to be less dependent on reading glasses
